Use this submenu to define backup as Auto (Automatic) or MAN (manual). This
setting allows automatic switching by the BU if both units are in Redundancy

This command is only accepted by the BU. If a chain converter is set to Manual
Mode, the BU logs the occurrence and does not act upon further information
from the converter until it is returned to Auto Mode.
On the top line, this line displays the unit in use and its Application ID
(identification label).
On the bottom line, use the keys to navigate to the AUTO/MAN setting,
and then use the ▲ ▼ keys to set toggle switch over as A (Automatic) or M
(Manual).

On the top line, use the keys to navigate to the OFFSET operational
threshold setting (i.e., the limit defined to automatically trigger switchover to the
backup unit), and then use the keys to set that value in 0.25 dB increments.
